If you are troubled by the reflection in the mirror, don’t be dismayed. Circles under the eyes are caused by your body, not your sleep habits! Your body is constantly breaking down hemoglobin, and sometimes the by products, which are dark like a bruise, pass through the capillary beds and will show through the translucent skin around your eyes.If you are also very tired, have pale skin, and have experienced memory problems, you may also be anemic, which is a very common health issue. If you are experiencing these symptoms you should seek the advice of your doctor. Getting good exercise and eating iron-rich foods such as red meat, hummus or baked beans may also be helpful.
